New rules target childhood obesity
A nationwide ban on junk food advertising has come into force across the UK, restricting when and where foods high in fat, salt and sugar can be promoted. From Monday, these products can no longer be advertised on television before 9pm or online at any time.
The measures are aimed at reducing childhood obesity by limiting children’s exposure to marketing for foods widely linked to poor diets. Products affected include soft drinks, chocolates, sweets, pizzas and ice creams, along with some breakfast cereals, sweetened breads, ready meals and sandwiches.
How products are classified
Whether a product is restricted depends on a nutrient scoring system that weighs overall nutritional value against levels of saturated fat, salt and sugar. Plain oats, most porridges, muesli and granola are not covered by the ban, although versions with added sugar, chocolate or syrups may fall within scope.
Food companies are still allowed to promote healthier alternatives, a move the government hopes will encourage reformulation and innovation across the industry.
Impact on brands and advertisers
While specific unhealthy products cannot be shown, companies are still permitted to advertise their brands in general. Logos, slogans and broader brand messaging remain allowed, meaning larger food chains with strong brand recognition may feel less impact from the changes.
Smaller food businesses, however, are expected to face greater challenges. Many rely on product-focused advertising to explain what they sell, and those campaigns will no longer be permitted if the products fall under the restrictions.
Enforcement and health context
The rules replace previous limits that only applied when more than a quarter of an audience was under 16. Any company that fails to comply now risks enforcement action by the Advertising Standards Authority.
Health data shows the scale of the issue: nearly one in ten children starting school are living with obesity, and one in five has tooth decay by the age of five. Obesity is estimated to cost the NHS more than £11 billion each year.
Expected outcomes
The government estimates the advertising restrictions could prevent around 20,000 cases of childhood obesity. Health experts say the move is overdue, arguing that children are particularly vulnerable to aggressive marketing of unhealthy foods.
Industry groups say they support the aim of improving public health and point to ongoing efforts to reduce salt, sugar and calories in products over the past decade.
